README

安装

composer require bingher/zipimg

使用

$input = 'path-of-image';
$zipimg = new \bingher\zipimg\Image();
$zipimg->zip($input);

# 助手函数
zipimg($input);

注意事项

• php.ini需要开启shell_exec函数

• windows环境 已经内置了压缩用的exe程序(32位),理论上直接用就行

• linux环境 需要编译安装pngguant,guetzli,mozjpeg

  • 安装pngguant

  # centos
  # libpng >= 1.6
  yum install libpng-devel
  git clone --recursive https://github.com/kornelski/pngquant.git
  cd pngquant
  ./configure --prefix=/usr/local/pngquant
  make && make install
  ln -s /usr/local/pngquant/bin/pngquant /usr/local/bin/pngquant
  

  • 安装guetzli

  #centos
  yum install libpng-devel
  yum install gcc gcc-c++
  mkdir guetzli && cd guetzli
  wget https://github.com/google/guetzli/archive/v1.0.1.tar.gz
  tar -zxvf v1.0.1.tar.gz
  cd guetzli-1.0.1
  make && make install
  ln -s 安装目录/bin/Release/guetzli /usr/local/bin/guetzli
  

  • 安装mozjpeg 官方教程 参考教程

  # centos 7
  yum -y install build-essential nasm
  
  # centos 8 安装nasm
  # 到https://www.nasm.us/pub/nasm/releasebuilds下载相关rpm包
  wget https://www.nasm.us/pub/nasm/releasebuilds/2.15/linux/nasm-2.15-0.fc31.x86_64.rpm
  yum localinstall nasm-2.15-0.fc31.x86_64.rpm
  
  cd ~
  wget -O "mozjpeg-3.3.1.tar.gz" https://github.com/mozilla/mozjpeg/archive/v3.3.1.tar.gz
  tar -zxvf mozjpeg-v3.3.1.tar.gz
  cd mozjpeg-3.3.1
  autoreconf -fiv
  ./configure --prefix=/usr/local/mozjpeg
  make && make install
  ln -s /usr/local/mozjpeg/bin/cjpeg /usr/local/bin/cjpeg
  

python服务

1. php客户端远程调用python服务端进行图片压缩

由于生产环境php一般会禁用执行命令行等危险函数,可以考虑用开启python服务端,然后php进行调用实现图片压缩

• 进入vendor/bingher/zipimg/python目录
• 安装python库

pip install -r requirement.txt

• 开启服务

python zipimg_server.py

• 远程调用

<?php
require_once '../vendor/autoload.php';

use bingher\transmit\Client;

$client = new Client('127.0.0.1', 8000);
$params = [
    'in_img'  => __DIR__ . '/input/1.jpg',
    'out_img' => __DIR__ . '/output/1.test.jpg',
];
$result = $client->zip($params);
var_dump($result);

# 助手函数
$input = __DIR__ . '/input/1.jpg';
$result = remote_zipimg($input);
var_dump($result);

2. python自动监控压缩图片

python ./auto_zipimg.py -w ../test/output -a ../lib/ -p
